Propelling mechanism for motor-driven vehicles.

ehds of which are connected :by a linlrv 34 and a lever`35, the extrernity of the latter being ,suitably connected with an operating rod (not shown). 'There is also provided, 'in

additionto these two hub brakes, a compensating gear brake 36, and this brake 36 is pro vided With a rolleror other suitable bearing 37, independent-o the stub shaft i9, and the bearing is carried upon an extension 38 which is stationary. rl`his construction hrings the braking strain on the statioi'iary member without any tendency to produce a bending or binding eect upon the rotating member, We have shown but one oi'l these bralrelirnnis l5 36, but preferably there will be a sir Llinly constructed one at the opposite side of the compensating housing 23. While the brake drum 36 is smaller than `the brake drain 112, it is equally as efficient, inasmuch as the shaft with, which it is connected rotates at much higher speed than the wheel which.

, i carries the brake drum. i2. Tse brake drums 36 are driven through suitable jaw clutches L10.

As illustrated in Fig. 3, the brake band di for the drum 36 is operated by a linlr 4t2 and lever 43. AThe rear axle housing 9B. is horizontally, which permits the ripper haii to be removed, and the compensating mech anism removed by 'withdrawing the stub axles 19 and 28.

inthe construction ci the mechanism for driving the propelling Wheels 4 4, the wheel can be removed lwithout disturbing the drive 'ing pinion 'l-O. The driving pinion can also be removed by data-ching theuniversal 'propeiling shalt 16, since the pinion and roller bearings are constructed. large enough in diameter to allow the pinion to pass through 40 the hole or passageway 6 which they ocenny when' in position. Y

From the foregoing description it will. be

see'n that it is o y' necessary 'for the pinion and Wheel axle to beI parallel in order to have t5 the drive taken .care oi under all conditions, and that the axes ci' the other driving wheel and other pinion do not need to coincide or be parallel With those of the iirst drive wheel, inasmuch as the drive from the compensat- R0 ing vmechanism to the pinion is ccminnnicated through the universal joints. As the projections on the end oi the uric 'which carry the pinion and axle spindles are made very strong and substantial, there is no possibility of the bending thereof to disturb the Aalinenrlent of the axis of the pinion and the axis of the Wheel'in any ordinary accident `or collision. Should the rear axle 1 be bent,

'or other ,displacement take placewhich will throw the axis' or' one driving Wheel out oi line with the other driving Wheel, the drive I Would'be .as 'eiiicient as though the axles were parallel, because of the `univer, a

nection between the compensating nischenn ism and the pinion.

split The housing 23 has its lower portion conn neoted with the iorward part e5 ci the velhicle through the medium oi radius rods Il@ lwhich have their forward ends pivoted at 47.
